Abstract: A digital electronic data system for use with a fluid dispenser which includes means for generating an electrical signal in response to each incremental quantity of fluid dispensed, the data system comprising manually setable register means for generating a static electrical signal representative of the unit price of the fluid being dispensed, computing means coupled to the dispenser signal generating means and the static unit price signal generating means for receiving the afore-mentioned signals and generating in response thereto signals representative of the quantity and cost of fluid dispensed. A data transfer means is connected to the computing means for receiving and accumulating static unit price, accumulated volume and price signals and transmitting the same serially through a signal transmitting medium.

Abstract: A batch controller for automatically and selectively controlling a plurality of material dispensers. The controller includes circuitry for metering, for slowing, and for terminating the flow of material in and at selectable quantity levels thereof. The apparatus includes a starting circuit that renders the apparatus inoperative in response to the absence or interruption of operating potential, and flow of the material is controlled by devices that provide fail-safe termination of flow in the event of failure.

Abstract: A solid state electronic alarm circuit including means for sensing a predetermined change in a parameter such as the temperature in a freezer or the like from a predetermined safe limit and means for generating an audible alarm in response thereto.

Abstract: An improved cartridge tape that is wound up upon a tape spool, and consisting of an endless tape located in a tape player cassette, the tape being able to be unwound from the center of the tape roll and wound up around the outer edge of the roll, so that either end of the roll can be fed for tape playing. The tape is enclosed in a housing having substantially identical opposite ends each of which is adapted to be received in a tape player. Means engaging the tape are interposed between the opposite ends of the housing for rotating the tape 180.degree. in a first direction and 180.degree. in the opposite direction whereby opposite sides of the tape are exposed at the opposite ends of the housing permitting intelligence to be recorded and "played back" on both surfaces of the tape.

Abstract: Disclosed is an energy conserving thermostatic control for use wih heating and/or air conditioning systems. The control includes solid state circuitry for automatically controlling or regulating the temperature of an area at at least two different selected temperatures at selected times and for selected periods. The control is compatible with conventional heating and/or air conditioning systems and in most instances can be installed therewith without modification or rewiring of the system.

Abstract: A small plastic dispenser, the sidewalls of the dispenser being manually collapsible. The top of the dispenser has a straw of resilient and flexible material connected thereto by which the contents of the dispenser can be discharged. The straw is foldable and collapsible so as to close the straw to fluid flow. The top has means thereon to hold the straw in a folded and collapsed condition. In a specific embodiment, the dispenser is integrally molded of a flexible and resilient material in the form of a container top and a container bottom. The container top and bottom have means thereon to form a liquid-tight seal therebetween after the dispenser is filled.
